LUBRICATOR FOR JOURNALS OF RAILWAY-WHEEL AXLES.

SPECIFICATION fOrming part of Letters Patent No. 398,556, dated February 26, 1889.

Application filed November 30, 1888x Serial No. 292,268. No model.)

To all whom, it may concern:

Be it known that I, Ennnr VAN DECAR, a citizen of the United States, and a resident of East Albany, in the county of Rensselaer and 1 State of New York, have invented certain new i and useful Improvements in Lubricators for Journals of Railway-\Vheel Axles, of which the following is a specification.

My invention relates to a lubricator for journals of axles of railway-wheels; and itconsists in the combinations of devices and elements hereinafter particularly described, and specifically set forth in the claim.

The object of my invention is to combine with a perforated walled cylinder mounted on a shaft and having its walls covered by a por- 3 ous cushion. of fabric which will receive and hold oil and transfer the same to the journal, f and also having its ends open to admit oil to 2 within the chamber of the cylinder, suitable 1 bearings which are connected or secured with l elastic cylinder-holding devices, whereby the l lubricating-cylinder can be readily introduced 1 within the oil-cellar of the axle-journal and i be elastically supported therein and in contact with. the periphery of the axle without 5 liability of shifting in either direction within the chamber of the oil-cellar. I attain these obj ects by the means illustrated in the accompanyingdrawings, forming a part of this specification, in which Figure l is a plan view of inyimproved lubricating device in place in the chamber of the oil-cellar. Fig. 2 is a side elevation of the same, with the walls of the oilcellar shown in section. and the lubricatingcylinder in place against the lower side of the journal of the axle. 3 is a cross-sectional View of an oil-cellar and journal of an axle and an end View of the lubricating-cylinder and its elastically-supporting bearings. Fig. 4 is a perspective View of the elastic cylinder-supporting device employed with the cylinder.

The same letters of reference refer to like 1 parts throughout the several views.

In the drawings, A represents the lubricating-cylinder, which cylinder is composed of the perforated metallic shell a and the outer porous cushion, which cushion covers the outer surface of the perforated shell a in all its extension. This cushion can be made of loosely-twisted yarn wound around the periphery of shell 0,01 ot' loosely-woven cloth or seamless knit fabric. or any other suitable material fitting nicely on the outside of the a little greater than the cylinder A, and has an extension about equal to the distance that the end walls, 0 c, of the cellar C are apart, so that said shaft will be received between the said walls without binding at its ends. The journal ends of shaft B are supported in bearings (Z (7. These bearings are shown in the drawings to be made in connection with the elastic supporting device D, made, pref.- erably, of spring-wire, (or a strip of spring metal,) and arranged within the chamber of the oil receptacle or cellar C, so as to hold the lubricating'cylinder central within the same and in contact with the journal J, as illustrated in Figs. 2 and 3. These elastic holding devices D are preferably employed in pairs, each device being made from a single piece of wire, as illustrated in Fig. *1, and when this elastic holding device is employed in duplicate, as shown in Figs. 1 and 3, they will be arranged opposite to each other within the chamber of the cellar, as illustrated in the same figures, so that each end of the shaft B will be supported by two bearings, as cl d, connected with the elastic coil, and bow made integral with the base limbs, as shown in Figs. 1, 2, 3, and it. hen in position, as shown in Figs. 1 and 3, these elastic supporting devices will hold the cylinder A central within the chamber of the collar, with its porous cushioned periphery a in situation for contact with the lower side of the journal J. hen oil or other liquid lubricant is introduced within the cellar C, it will readily enter into the chamber of the cylinder A through the open head ends, (1, when. the oil within the cylinder will have passage through By the improvements in my above-described invention the lubricating-cylinder and its elastic supporting devices can be adaptedto be readily applied to the cellars or oil-boxes of journals of car-axles and also to those of the Without necessitating any changes Whatever in the construction of the oil cellars or boxes, and the devices will be securely held Within the cellar from displacement, with the lubrieating-cylinder free to revolve in contact with the surface of the journal to be lubricated, While the lubricating material will be positively transferred to the porous cushion a from both of its sides and by itbe transferred to the surface of the journal.

Having; described my invention, what I claim, and desire to secure by Letters Patent, 1s

The combination, with the lubricating-cylinder A, constructed of perforated metal a,

r and porous outer cushion, covering the former, and mounted on shaft B, and having open end heads, of the bearings cl cl, supported by the elastic holding devices D, constructed, substantially as described, for operation and purposes as set forth. journals of the driving-shafts of locomotives EMER Y vAN DECAR.
